وَلَو نَشاءُ لَأَرَيناكَهُم فَلَعَرَفتَهُم بِسيماهُم ۚ وَلَتَعرِفَنَّهُم في لَحنِ القَولِ ۚ وَاللَّهُ يَعلَمُ أَعمالَكُم

If We had willed, We would’ve shown them to you, and then you would’ve identified them by their marks. But you will recognize them by the tone of their speech. And God knows your deeds.
